The Philips Collection

There's another reason to visit Washington DC this winter.  I didn't know this but The Philips Collection museum is America's first museum of modern art since 1921.  

Currently on exhibit from now through January 11, 2015 is Neo-impressionism and the Dream of Realities.  
From the website (http://www.phillipscollection.org/exhibitions):

With more than 70 paintings and works on paper this exhibition demonstrates how the Neo-Impressionists employed stylization and a deliberate orchestration of color to create landscapes and figures that went far beyond observed nature.
